DXA scanning in clinical practice

Review DXA scanning in clinical practice

Dual-energy X-ray absorptiometry (DXA) is recognized as the reference method to measure bone mineral density (BMD) with acceptable accuracy errors and good precision and reproducibility. The World Health Organization (WHO) has established DXA as the best densitometric technique for assessing BMD in postmenopausal women and based the definitions of osteopenia and osteoporosis on its results. DXA...

Monitoring DXA Measurement in Clinical Practice

Interpreting a DXA Scan in Clinical Practice

Osteoporosis is a metabolic bone disorder characterized by low bone mass and microarchitectural deterioration, with a subsequent increase in bone fragility and susceptibility to fracture. Dual-energy x-ray absorptiometry (DXA) is recognized as the reference method to measure bone mineral density (BMD) with acceptable accuracy errors and good precision and reproducibility(Blake and Fogelman 2007...

Frequency of Errors in Clinical Laboratory Practice

  Background and Objective: Laboratory errors are one of the major factors that affect the diagnosis, prognosis, treatment and monitoring in patients.The objective of study is to evaluate the frequency and type of errors in different phases of testing at the Pathology Department of the Shalamar Hospital, Lahore and to evaluate the causes of errors. Methods: This observational study was carrie...

Clinical applications of body composition measurements using DXA.

Dual-energy X-ray absorptiometry (DXA) scanning was primarily developed for the diagnosis of osteoporosis and was initially applied to studies of the clinically important sites of the lumbar spine, femoral neck, and forearm. The rapid adoption of DXA has led to the development of different, competing generations of equipment. Improvements have been achieved through advances in X-ray generation ...
